How to get CPU usage

Hello,
I was confident I could use OS.execute (‘top -n1’) from a luup script until I realized that OS.execute does not return the output of the command. How could I do this?

Try io.popen() instead, although top may need special params unless it can only show one cycle of output.

You could try to pull the info from /proc.

I have tried that but I am not sure this is available.

Yes this is an option but it brings us back to io.popen
